Another theme is mutual understanding. Despite their different personalities, they seem to understand each other on a level that others don't. Fanfics often play on this, showing how they can communicate without words at times. For example, in some stories, Levi can tell when Hanji is about to do something reckless just by a look in her eyes. And Hanji can sense when Levi is more stressed than usual. This mutual understanding forms the basis of many emotional and plot - driving moments in the fanfics.
Another one is 'Hanji's Perspective on Levi'. This fanfic is unique as it is told from Hanji's point of view. It gives readers a different look into how Hanji sees Levi, their quirks, and the special connection between them.
One common theme is friendship. Their relationship, whether it's portrayed as a deep platonic bond or something with a hint of more, is often central. They support each other through tough times, like in battles or when dealing with the politics within their group.
In lemon fanfiction, Levi is often depicted as being very in - control on the surface but secretly having a soft spot for Hanji. His stoic nature gives way to passion in these stories. Hanji, on the other hand, is usually portrayed as being more open - minded and eager to explore the relationship. They both bring out different aspects of each other's personalities.
One common theme is the adjustment to parenthood. Both Levi and Hanji are strong characters in their own right, and seeing them navigate the new world of diapers, sleepless nights, and baby giggles is really interesting. Another theme is the growth of their relationship. Having a baby often brings a couple closer, and in these fanfictions, it shows how they support each other through it all.
The fact that they are comrades in the Survey Corps also adds to their popularity as a couple in fanfiction. They have a shared history, they've been through battles together, and they understand each other's traumas. This deep connection based on shared experiences is often explored in fanfiction in the context of a romantic relationship. For example, in many stories, they find comfort in each other after a particularly difficult mission. They know how the other feels because they've both lost comrades and faced the Titans. It gives a very strong foundation for a romantic relationship in fanfiction.
